hi mk,
I know that feeling and I guess we all do. Nobody can have a perfect timing and buy the exact bottom or sell the exact high.
one tip is not buying ALL at one point. split it in 4 or more parts and start buying and then watch which direction it is going. wait for it to come back. don´t chase it.
same now. don´t sell with a loss. it will go to 13.00 and higher again. I am sure you will be green at some point. we do not know when, but it will happen.
if you have more cash try to add and lower your average. or just wait it out.
don´t worry, it will be ok. this stock was at 32 dollar last year when gold hit 1380. we may eventually see 25-30 again this year.
good luck
